What PVD Coating Stainless Steel Products should Pay Attention?

1. Although vacuum PVD film has a certain corrosion resistance, it is difficult to resist in the face of acid and alkali and other highly corrosive substances.Accordingly, when maintaining at ordinary times, as far as possible do not choose contain strong acid strong alkali or decontamination ability strong cleaning agent, such as clean toilet essence, take off paint agent, metal cleaning agent, can choose industrial alcohol with soft cotton cloth gentle wipe, if the surface has dirt, also want to choose weak acid weak alkali solvent to deal with.In addition, if exposed to harsh environment for a long time or in contact with corrosive liquid for a long time, PVD film is also prone to fall off and other problems, such as swimming pool (containing fluorine), seawater (containing much salt), high temperature and humidity (steam) and other environments.

2. Use of anti-fingerprint varnish.More and more customers choose to plate good color PVD film layer of stainless steel products, and then spray a layer of transparent anti-fingerprint oil, the effect is very obvious, there is no fingerprint on the hand, easy to clean, can also increase the wear and corrosion resistance of the function, multiple.However, the disadvantage is that the color of injection oil and no injection oil is inconsistent, plus the processing requirements are high, the cost is not low, affecting the metal texture of the product, there are aging and other problems.Therefore, the use must be carefully considered.

3. The processing problems. PVD film has a very good adhesion with the substrate and is not easy to fall off. The product can be followed by simple mechanical processing, such as cutting, folding, bending and cutting.However, welding on the PVD film is very big, instantaneous high temperature will lead to the film off and discolor, therefore, need to weld stainless steel products to plating color, it is best to do the components before plating color, can not be used to plating PVD film material to process products.The welding scar that color product leaves is handled hard, optional finished product is made process should be first weld component, undertake burnish next, purify welding scar, undertake plating color again finally.
